Abstract

L'invention concerne un autoclave (100) destiné à l'oxydation sous pression d'un matériau en suspension comprenant au moins un matériau sulfure, et un procédé. L'autoclave (100) comprend un récipient sous pression (1) destiné à recevoir ledit matériau en suspension. Le récipient sous pression (1) comprend des compartiments (2a-2d) disposés horizontalement l'un après l'autre et séparés par un ou plusieurs diviseurs (3). Le diviseur (3) est pourvu d'un bord supérieur (4) ou d'au moins une ouverture qui délimite le niveau (L) du matériau en suspension dans le compartiment (2a-2d). Une entrée (15) est ménagée pour l'alimentation en gaz contenant de l'oxygène dans le récipient sous pression (1). Un agencement d'agitateur (6a-6d) étant agencé pour agiter ledit matériau en suspension dans au moins l'un des compartiments (2a-2d), l'agencement d'agitateur (6a-6d) comprenant au moins un impulseur supérieur (7) et un impulseur inférieur (8), les impulseurs étant agencées dans sur arbre aligné verticalement (9). L'impulseur supérieur (7) est disposé à une hauteur au-dessus du niveau médian (M) dudit compartiment (2a-2d), et l'impulseur supérieur (7) est un impulseur à écoulement axial ou à pompage vers le haut.
